Complete Mobile Filtration Solution for Hydraulic and Lubrication Systems
Maintaing the cleanliness of hydraulic fluids and lubricants is critical for the longevity and efficiency of industrial machinery. The Eaton UM 20 Hydraulic Offline Filtration System represents a premier solution for mobile oil maintenance. Designed to operate independently of the main system verify, this unit excels at removing solid particles and water from fluids, ensuring that your equipment runs smoothly and unplanned downtime is minimized.

What is the Eaton UM 20?
The Eaton UM 20 is part of the UM series of mobile offline filter units. Unlike in-line filters that only clean fluid while the main system is active, this offline unit draws fluid from the reservoir, filters it, and returns it, providing continuous purification regardless of the machine’s operating state. This makes it an ideal tool for secondary flow filtration, fluid transfer, and cleaning up new oil before it enters your system.
Key Features and Benefits
- Compact and Portable: With a structural design optimized for tight spaces, the UM 20 is easy to maneuver to difficult-to-access areas in a plant.
- High Efficiency Filtration: The unit typically utilizes high-quality Glass Fiber Fleece (VG) element media, capable of ensuring high cleanliness classes.
- Dual Functionality: It is designed to remove both solid particulate contamination and, with specific elements, water content from the oil.
- Tool-Free Maintenance: Filter elements can be replaced easily without the need for special tools, reducing maintenance time.
- Safe Operation: Integrated safety valves permit unattended operation, allowing technicians to focus on other tasks while the oil is being polished.

Ideal Applications
The Eaton UM 20 is versatile and serves a wide range of industrial applications. It is particularly useful for:
- Hydraulic Power Units: Keeping reservoirs clean to protect sensitive servo valves and pumps.
- Lubrication Systems: ensuring gearboxes and bearings receive contaminant-free lubrication.
- Transfer Pumping: Filtering new oil as it is pumped from storage drums into system tanks (new oil is often dirtier than required specs).
- Periodic Maintenance: A cost-effective mobile solution that can be shared across multiple machines in a facility.
Why Choose the Eaton UM 20?
Investing in an offline filtration system like the UM 20 leads to direct cost savings. By extending the service life of your hydraulic fluid and system components, you reduce the frequency of fluid changes and the cost of spare parts. The unit’s ability to continue filtering during tank filling ensures that no contaminants enter the system during maintenance intervals.
By leveraging high dirt-holding capacity elements, the UM 20 remains effective for long periods, providing a reliable defense against wear and tear caused by particulate matter.
